Abstract

Background: The efficacy of germinated barley foodstuff (GBF) on tumour necrosis factor-alpha (TNF-?), interleukin-6 (IL-6) and -8 (IL-8) in patients with ulcerative colitis (UC) has not yet been examined. The aim of the present study was to determine the effect of administration of GBF on serum TNF-?, IL-6 and -8 levels in UC patients in remission. Methods: Forty-one patients with UC were divided into two groups, namely control and GBF group. Twenty-one patients in the control group received standard treatment while 20 patients in the GBF group received 30 g of GBF daily by oral administration during two months of the study along with standard drug therapy. Results: Levels of TNF-?, IL-6 and -8 all decreased in the GBF group compared with baseline during the two-month study, while in the control group all values rose. For IL-6 and -8 this effect was significant, P = 0.034 and 0.013, respectively. Conclusions: The results of the present study showed that the consumption of GBF may reduce the level of serum TNF-?, IL-6 and -8 in patients with UC. This investigation was designed as a pilot study and the results may provide a basis for more future clinical trials.
